Hi all Special thanks to Myke Predko and Todd Peterson for their responses to my posting and Myke's help on getting MPLAB to work with the Picstart Plus programmer. It finally seems to work now. >>I wanted to upgrade to MPLAB v3.10 because this was supposed to >>support my newly aquired PCB & PCM C compilers from CCS. Only now >>that I upgraded, I find that I can't communicate with the PICSTART >>Plus programmer anymore. I am using the recommended Picstart plus >>software v1.20.07. >> >>Does anybody else have the same problem, or is my Picstart Plus >>programmer faulty? I know there is also an upgrade hex file >>available from the Microchip website for upgrading the firmware, but >>I assumed this was only neccessary if you wanted your programmer to >>support all the latest hardware. Will my problems dissapear if I buy >>a new 17C44 and upgrade my firmware? >> >>I'm going to try and go back to my previous version of MLAB V3.01 >>now, because version 3.09 is no longer available from Microchip's.. >>website. Hopefully my programmer will start to work when I do this, >>but this seems to be my only hope.... or is it? >Can someone perhaps shed the light of experience on this? I too would >like to use the CCS PCM C Compiler with MPLAB, but have heard of >trouble from the latest version of MPLAB. I also thought so at first, but the PCM complier does work with the MPLAB v3.10. Even though the PCB compiler is not listed when you select add/modify in the edit menu, you can still add it manually by typing in PCML on the command line. >Also, what will using a new 17C44 do for the Picstart Plus? As far as I can tell, you get to program some addtional devices not supported in the older version. I haven't really made a comparison as to exactly what devices, but I seem to recall reading that somewhere in the documentation. It might be worth the trouble after all. >I don't believe the CCS C Compiler can be used with version 3.09, can >it? According the customer support people at CCS, yes it can.
